j This invention relates to a water circulator adapted to be used in conjunction with a water cooling system for an internal combustion engine and it consists in the novel features 5 hereinafter described and claimed.

An important object of the invention is to provide means for utilizing the pulsation or force of the exhaust of an internal combustion engine for the purpose of circulating water through the cooling jacket oi the engine, so that the temperature of the engine is held at a relatively low degree, owing to the fact that vthey water passing ra idly through the cooling jacket absorbs the eat from the cylinder.

lln the drawing Figure 1 is a vertical side elevational view of the water cooling system with parts thereof shown in section;

Figure 2 is a vertical casing used in the system.

Asillustrated in the accompanying drawsectional view of a ing, the numeral l() designates the water jacketed cylinder of an internal combustion engine and 11 the head thereof. An inlet pipe l2 connects with the water jacket of the cylinder and said pipe also connects with an opentopped tank 13 or other suitable source of water supply. 3o valve 14. Apipe 15 also connects the jacket of the engine with the source of water supply.

A casing 16 islocated adjacent the end of the engine cylinder and a pipe 17 connects the casing 16 at a point between the ends thereof with the pipe 12. The pipe 17 is provided with a check valve 18 and a globe valve 19. The check valve 18 closes in the direction of the water jacket of the engine, as indicated by the arrow in Figure 1. A pi e 20 connects one end of the casing 16 with t e interior of the cylinder of the engine 10 and the said pipe 20 passes through the head 11 of the water jacket of the said engine. A pipe 2 1 is connected with the up er end of the casing 16 and extends upwar ly and then down and is connected with the lower portion of the water jacket of the engine 10. The pipe 21 is provided with a valve 22. The casing is provided with a relie valve 23. The casing 16 is pro- 50 vided in the vicinity of its upper end with an portion of the casing The pipe 12 is provided with a` interiorly located transversely disposed partition wall 24 havingat its center a valve seat 25. A by-pass pipe 26 is connected'at one end with the casing 16 at a point below the wall 24 and connects at its other end with the pipe 21 at a point above the upper end of the casing 16. The by-pass pipe is provided with a valve 27. A check valve 28 is slidably mounted in the casing 16 and is adapted to engage the seat 25 in the wall 24.

lt will be seen that when the exhaust is expelled from the cylinder of the engine 10 through the pipe 20, it first passes through the water which is contained under the head 11 of the engine. It then enters the casing 16. From the casing 16, it may pass through the seat of the partition wall 24, then through the pipe 21 to the water jacket of the engine..

'At the same time, the valve 19 in the pipe 17 may be opened, so that water will be permitted to flow through the pipe 17 into the lower` 16. This water is carried by the exhaust from the engine up through the pipe 21 and is caused to How into the jacket of the engine cylinder. The stream of water and exhaust which enters the water jacket of the engine will cause the waterin said jacket to circulate around the cylinder of the engine and cool the same. The water which is contained within the water jacket of the engine is originally supplied through the pipe 12 and when heated in the water jacket, may flow through the pipe 15 back to the source of water supply.

Since the construction hereinbefore set forth is capable of a certain range of changev and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.

I claim ln combination with a water jacketed internal combustion engine, means for circulating water through the jacket thereof consisting of a connection between the jacket of the engine and the interior of the cylinder including a casing having a check valve arranged therein, a connection between the water jacket and said casing includin a check valve closing toward. the water jac ret, said connection communicating with the casing between the check valve and the end of the casing which is in communication with the cylinder, the connection between the cylinder and the water jacket being free from communication with the atmosphere.

In testimony whereof I hereunto affix my signature.
